BRUSSELS, Sept 30 (Reuters) - The European Union's
statistics office slightly revised upward its September core
consumer price inflation estimate to 0.8 percent year-on-year
from the 0.7 percent it announced earlier on Tuesday, down from
0.9 percent in August.

The headline inflation estimate for September remains
unchanged at 0.3 percent year-on-year, down from 0.4 percent in
August, Eurostat said. An official at the EU agency said the
revision to core inflation, which excludes energy and
unprocessed food prices, was due to a rounding error.
